SCOPE This specification defines the performance requirements for sewing threads used in functional and decorative purposes for interior trim vehicle components. 2. APPLICATION This spe

3、cification was released originally for material used in sewing operations in the manufacture of interior trim vehicle components. Table 1 indicates recommended usage per thread size (Tex/Metric-M) and fiber content. Other applications not listed in this table will be considered after evaluation by M

4、aterials Engineering based on the proposed use. Nylon is the recommended fiber content. Certain regions (for example China) may require the use of polyester due to fiber availability. Polyester thread will be required for areas of high UV exposure such as Instrument Panels (IPs) for decorative stitc

5、hing. WSS-M8P25-C contains the typical lubricant on the thread as selected by the thread supplier. WSS-M8P25-D is produced dry to aid in the shift boot component level testing for liquid penetration. 3. REQUIREMENTS Threads to be used in the application of serging and embroidery for floor mats must

6、meet WSS-M8P22-A, Performance, Floor Mat, Serge and Embroidery Thread. In addition, specific material specification WSB-M15H64-A/latest will need to be met based on application use. 3.1 APPROVED SOURCES This specification requires the use of approved sources. Only the sources identified on the Ford

7、Approved Source List (ASL) can be used when this specification is listed on the drawing, CAD file, or other documents. The list of approved sources is located within Ford at or available externally through a Ford Materials Engineer. 3.2 APPEARANCE The color, pattern, and finish shall match the appr

8、oved Corporate Design master sample 3.3 BALANCE Take a one meter length of sewing thread drawn freely from the side of the spool (without undue tension and without passing it through any restriction such as fingers, etc.) and bring the thread together to form a free hanging loop. In this position, t

9、he thread must not twist upon itself more than twice. 3.4 NUMBER OF KNOTS The thread spool shall be free from all imperfections of such character which would cause the thread to break during sewing.

15、ing test conducted under normal production conditions. The thread must process under production conditions without any reservations and meet the sewn seam requirements of the cover material specifications. Suppliers deliveries can be rejected because of excessive rates of breakage and/or other manuf

16、acturing difficulties (knots, foreign matter, etc.). In addition, after sewing, the thread shall not exhibit objectionable streaks or any change in hue or purity of color, or transfer residue. 4. GENERAL INFORMATION The information given below is provided for clarification and assistance in meeting

17、the requirements of this specification. Contact for questions concerning Engineering Material Specifications. Drawing call-outs shall state Thread Type Designation and Size. Examples would be: WSS-M8P25-A/N90, WSS-M8P25-A/Tex 90/Nylon or WSS-M8P25-A/M30/Nylon Refer to Table 1 for Thread Type Design

18、ations. N90= Nylon, Tex90/M30. 4.1 Purchase departments will ensure that the material defined in this specification and shipped to any one assembly plant will be produced by one supplier only. In the event of a Global Program or Regional duplication, each regional location of the supplier for this s

19、pecification must provide a construction package and be approved to meet this specification. 4.2 APPROVAL OF MATERIALS Suppliers desiring approval of their materials shall first obtain an expression of interest from Purchasing, Design or Product Development, and Materials Engineering. The supplier s

20、hall submit a completed copy of their laboratory test reports, signed by a qualified and authorized representative of the test facility, demonstrating full compliance with all the requirements of the Material Specification. Tested material samples must be available for review upon request and kept f

21、or a minimum of one year. Upon request, the supplier will review the associated quality control documents (Process Failure Mode and Effects Analysis, Control Plans, Certification testing) with Ford. 4.3 SUPPLIERS ONGOING RESPONSIBILITY All materials must be equivalent in all characteristics to the m

22、aterial upon which approval was originally granted. Prior to making any changes to the material originally approved, whether or not such changes affect the materials ability to meet the specification requirements, the supplier shall notify the affected Supplier Technical Assistance (STA), Purchasing

23、, and Materials Engineering activities of the proposed changes (with reasons) by submission of a completed Suppliers Request for Engineering Approval, SREA. For parts and components using Ford Engineering Material Specifications, all samples tested to the specifications for Design Verification (DV),

24、 Production Verification (PV) and Producation Part Approval Process (PPAP) sign off must be kept until Job 1. 4.4 RESTRICTED SUBSTANCE MANAGEMENT STANDARD Substance restrictions imposed by regulations or Company direction applies to the materials addressed by this document.
